This product is not made as the withstand pressure
structure. Ensured pressure value of the Pump shall be
0.03MPaG (0.3kg/cm2G) (Gauge pressure).
・
Do not run the Pump on blocking the Exhaust outlet or
putting any device that might hamper gas passage onto the
outlet. There is a risk that the pressure inside the vacuum
pump rises up to cause break the casing or Oil level gauge
resulting in overload of the motor.
